I got whiffs of it on the train ride to Park Slope… a soft, yet pervasive odor that smelled something along the lines of old popcorn, Fritos, and this $9 bottle of cologne I bought at Walgreens when I was 16. I don't know if there's something anatomically different between regular sweat and post-workout sweat, but whatever it is, it's bad.
This odor stained everything it touched, like when you spill milk in the back of a car and it takes weeks for the smell to come out. My shirt reeked, my skin smelled, and I couldn't stop sweating.
Did anyone notice? Yes, everyone noticed. I soon learned that over-explaining why you smell bad to your friends will only make you more self-conscious, which in turn will only make you sweat more, which will only make you smellier. I consider week two to be the smelliest I've ever smelled. So that's an achievement in itself!
